TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 235,102, dated December 7,1880,

(No model.)

To all whom it may concern:

Be it known that I, SAMUEL SEcRnsT, of Byesville, in the county of Guernsey and State of Ohio, have invented certain new and useful Improvements in Turbine ater-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference beinghad to the accompanying drawings, which form part of this specification.

My invention relates to certain improvements in turbine water-wheels, and is designed to provide a form thereof which will be simple in construction and effective in operation.

According to the invention a vertical rotating shaft is fastened to a central plate, which is connected by radial arms with the lower one of two rims, between which latter the buckets are secured, said buckets being made of sheet- -iron, and having their inner extremities respectively formed with outwardly-bent extensions adapted to be adjusted laterally to and from their buckets, according to the volume of water which is desired to be brought against the wheel. The chutes are secured between an upper rim and a bottom plate, which latter is centrally perforated to fit over the wheel.

These chutes have their outer extremities piv-' otall y secured in position, while their inner extremities are adapted to be moved inwardly or outwardly, and thereby determine the volume of water to bepassed through the chutes and operateupon the buckets. The upper portion of the wheel is steadied and the inside wheel maintained in position by a spider having the outer extremities of its arms secured to the inner wheel, and having its hub fitted on the shaft of the wheel.

In the drawings, which represent parts sufficient to understand the invention, Figure 1 is a perspective view. Fig. 2 is a central vertical sectional view. Fig. 3is ahorizontal sectional view, and Fig. 4 is a detail view illustratingone form of lock for maintaining the chutes in adjusted position.

The vertical rotary shaft A is provided with a bearing, a, adapted to be fitted in a suitable step, and also has its lower extremity provided with an angular section, I), which fits in a corresponding opening formed in the plate the wheel.

B. Arms 0 extend from this plate to the lower one of the two rims, D, between which the buckets E are secured. These buckets are made of sheet-iron, and are respectively provided with adjustable extensions 0, the latter consisting of the inner extremity of the bucket formed in a return-bend, which can be adjusted laterally to or from the main body of the bucket. This adjustment is effected by the hand or any suitable implement, and the rigidity of the metal is sufficient to maintain the extensions in such adjusted positions. Practically it is found that the impact of the water is not so great as to force the extensions of the buckets out of position.

When the extensions partially close the passage of water through the buckets, the Wheel is revolved at a less rate of speed than when the extensions are adjusted so as to permit a full sweep of water through the buckets. In this manner the current of water acting upon the wheel may be regulated so as to drive the latter with greater or less speed and force.

The chutes F are secured between an upper rim, G, and a bottom plate, H, the latter being centrally perforated to fit over the rotary shaft. The water is directed by said bottom plate through the several chutes and against the bucket. The chutes have their outer extremities pivoted in position, while their main bodies are adapted to be adjusted inwardly or outwardly. The passage -way between any two chutes can thus be made greater or less, as desired, in order to permit a large or small volume of water to act upon the buckets of Each chute may be maintained in adjusted position by any suitable means. The form shown in the drawings consists of a vertically-sliding catch, d, secured to the free swinging end of the chute and engaging with a curved series of holes, 6, formed in the bottom of the plate H. A spider has its hub, K, loosely fitted on the wheel-shaft, and its arms L have their outer extremities connected to the top rim of the inner wheel. The upper portion of the entire wheel is thereby steadied, and the inner wheel is maintained securely in position.

The operation of the invention is apparent.

Water falling from above on the horizontal wheel flows upon the bottom plate, H, radially outWa-rd through the chutes. The latter be laterally adjusted to or from the main body directthe water againstthe buckets, and thence. of the buckets, substantially as set forth. it leaves the wheel by an external flow. The 2.
